ATTACHMENT FOR VEHICLE-LAMPS.

To all whom it may concern:

- Be it known that I, HARRY A. VL'EIWIS, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new anduseful Improvements inAttachments for Vehicle Lamps, of which the following is a full, clear, and exact description. p My invention relates to attachments for use on the lamps employed on vehicles such as automobiles, motorcycles and the like. Its object is to provide a vizor or hood that will extend in front ofthe lamp a distance sufiicient to break up the straight beam of light thrown from the reflector and yet permit a portion of the radially reflected rays to be cast upon the roadway several feet in front of the vehicle so that the: driver can readily observe the condition of his path.

A further fobject of this invention is to provide a vizor attachment that is removable from the lamp so that it may be readily attached to lamps at present in use.

These objects I accomplish by the means and in the manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawing forming a part hereof, in which Figure 1 is a vertical side elevation of an automobile or motor-vehicle lamp showing my improved attachment in position thereon. Fig. 2 is a vertical front elevation of the lamp and my attachment. Fig. 3 is a view similar to Fig. 1, having the rear portion of the lamp broken away, and showing a modified construction of my improved attachment. j

Referring to the drawings, 1 represents the body portion or casing'of a vehicle lamp of any well-known type that is p referably cylindrical or tubular in shape and has its rear end permanently closed by the ordinary reflector.

2 is a suitable annular frame correspond ing in'shape to the transverse dimensions of said lamp and is provided with a glass plate to form a door for closing the front end of the lamp and which is mounted, by means of a hinge 3, on the body portion of the lamp, as shown. This door is provided, around its edge next to or contacting with the lamp, with a circumferential head 4:.

My improved altaclnnent preferably comprises a suitable semi-dome shaped VlZOI or hood .llmt projects a considerable distance Specification of Letters Patent. Application filed July 29, 1911. Serial No. 641,236.

door and has its horizontally disposed lower edge 6 in a plane approximately striking through the burner tips of the lamp .while its rearedge is in a vertical transverse plane at right angles thereto. The rear portion of the VlZOI is preferably arched in shape, corresponding in outline to the exterior di- -mension of the door so that it will fit snugly on the outside of the same. Depending from the lower rear corners of the vizor are suit,

able narrow straps or bands 7- that are preferably formed integral therewith. These straps are adapted to be bowed around under the lower portion of the lamp door 2. where they are each bent laterally outward at right angles to themselves to form suitable clamping lugs 8, 8, through which a set or thumb-screw 9 is tapped.

In adapting the device to a lamp already in use itis necessary only to fit the same around the door and tighten the same until the adjacent ends of straps 7 have been brought close enough together to be engaged by the set-screw 9 the adjusting of which will securely clamp the device in position.

In the modification shown in Fig. 3 the door 10 of the lamp is of the same construction as that shown in Figs. 1 and 2 eXccPting that the upper portion is preferably extended beyond the vertical plane of the door to form an integral vizor or. hood ll that occupies the same relative position. as that shown in the other two figures. In this construction, however, the attachment is a part of the door and cannot be removed.

From the above it will be seen that when the lamp is lighted the flame from. the

burner tips within the lamp body will projectabove the horizontal plane of the lower portion of the vizor and the lamp will not throw a straighthorizontal beam in front of the same but the rays will be deflected and thrown downwardly upon the roadway. This will prevent pedestrians and the drivers of other vehicles from becoming blinded or dazed v owing to theintense'light that is ordinarily projected from lamps of this character.

What I claim as new is 1. An attachment for lamps comprising a suitable door in front thereof having a viz r or hood projecting forward from the upper part of the rim portion thereof and adapted to intercept the upwardly radiating rays 0' light from the source of light, said vizor pro,

vided with depending straps that removably clamp the same to said door.

2. An attachment for vehicle lamps consisting of a vizor that projects in frontof said lamp and provided with integral depending straps that removahly clamp said vizor tosaid lamp.

3. An attachment for vehicle lamps consisting of asemi-dome shaped vizor that projects in front of said lamp and provided with depending straps that removably clamp said vizor to said lamp.

4. An attachment for vehicle lamps ,con-

s'isting of a semi-dome shaped vizor that projects in front of said lamp the lower 15 edge of saidvizor being in the horizontal plane of the source of light, and straps depending from the rear ends of said vizor that are adapted to engage said lamp and removably clamp the vizor thereto. 20 In Witness whereof I have hereunto set my hand this 24th day of July, 1911.
